Conferences, speaking engagements, and projects - oh my!
Life has been busy at Envision Lighting Design. I'm going to try to get back into the habit of sharing it all with you here on the blog. There have been many recent inspirations, but I'm going to start with bringing you up to speed on one of my favorite bonus activities - the IES.

This year I am the chairperson of the IES EP Event. This is a day-long workshop designed for students and emerging professionals interested in the lighting field. During the event we provide tons of interaction between seasoned and emerging professionals in lighting. It is truly one of the most energizing and dynamic groups of people I know. This year's EP Event is being held in conjunction with the IES Annual Conference in Pittsburgh on November. 1 The Event will extend beyond our Saturday workshop with ongoing activities and interaction planned throughout the Conference, which will end on Tuesday November 4. If you have any questions about this event, contact me. I absolutely love to talk about it.

As chair of the EP Event, I'm also a part of the IES Annual Conference steering committee. We are busy selecting speakers and planning events for the conference to get just the right balance of education, networking, and entertainment. If you haven't been to an IES Conference in a few years, you should plan to get to this one. The talent we are bringing in this year will blow your mind! This is not your daddy's IES Conference.

Mark your calendars!

Next post: I'll fill you in on our latest St. Louis IES section meetings, and more!
co-lor  tem-per-a-ture: noun The temperature at which a black body radiator emits radiation of the same color as a given object.

You may or may not be able to understand the definition of color temperature, but you know it when you see it. The two luminaires in this photo both have compact fluorescent lamps in them. 

Saving energy = saving money = good. 
Mismatched color temperatures = bad.

The one on the left is a cooler color temperature than the one on the right. A cooler color temperature has a higher number, measured in Kelvin, while a warmer color temperature has a lower number. These two are around 3000K and 2700K. When shopping for replacement lamps, make sure to get consistent color temperatures, and decide ahead of time whether you want a warm color like incandescent or a cooler, "whiter" light.

The City of St. Louis turns 250 years old this year! In fact, it's such a monumental birthday that we are celebrating all year long! There will be a ton of fun activities happening in and around the city this year, including Cakeway to the West, a regional art project featuring 250 fiberglass birthday cakes. But considering the historic nature of this milestone, it is no surprise that one of the biggest participants is the Missouri History Museum. Envision Lighting Design is proud to be a part of the Missouri History Museum celebration as the lighting designer for the upcoming exhibit 250 in 250.
This must-see exhibit is going to be a real treat! It features 50 People, 50 Places, 50 Images, 50 Moments, and 50 Objects of significance over the past 250 years of St. Louis history. Can you guess what some of them might be? Check it out; There are sure to be a few surprises in there. No excuses - the free exhibit will be open for a whole year, from February 14, 2014 until February 15, 2015. 
It was another amazing IES Annual Conference! This year, I have to say the pre-conference Emerging Professional Workshop initiated the energy that propelled me through the rest of the conference! If you are not a part of the EP workshop, I feel sorry for you! If you want to be a part of it next year, contact me! We want to host 100 Emerging Professionals next year, which means we need even more experienced lighting professionals to participate and interact during the event

The Sunday night Awards event was beautiful, with a record-setting 29 projects receiving Illumination Awards this year! For me, one of the highlights was seeing my old friend Kelly Jones who received an Award of Excellence for one of her projects. It was also fantastic to see Kristin Peck accept an Award of Distinction! Kristin was an intern when I worked at LDA (a lifetime ago) and her award-winning project was the first one designed by her new firm PrichardPeck Lighting. Congratulations Kelly and Kristin!

Monday morning's keynote address by Ekaterina Walter was on the topic of social media. This is an area where our industry as a whole lags, but I was personally inspired by her talk. There is no B2B; because of social media, business is all P2P. People to people. Number one takeaway: remember to "delight" your audience.
  1. Create great content
  2. Add value
  3. Build tribes
  4. Inspire movements

I was mostly attracted to papers and sessions that focused on lighting and health. Asha Hedge spoke about Sensory Processing Disorders and how lighting design - especially for schools - can accommodate students who fall under the umbrella of Autism Spectrum Disorder or have other types of Sensory Processing struggles. The research in this field is minimal. What is available is sometimes contradictory and often based on anecdotal evidence. I believe this is a field which deserves more study, and the more we learn, the better environments we can create for everyone, not just those who have special needs. Lighting is for people. We need to create appropriate environments for all people.

The next general session was a fairly technical discussion about lamp lumen depreciation with LEDs. So many of our old metrics don't apply to LED technology, and we are playing catch-up as the researchers attempt to define new metrics. For example, what LLD factor do we apply to products that increase drive current over the life of an LED to avoid any lumen depreciation? Products with higher drive current could look identical to a lower drive current product at the beginning of life but will depreciate faster. What about driver failure? This isn't a part of a lumen depreciation calculation, but should it be a part of lamp life calculations? This general session was a great illustration of how the conference is turning back toward its "technical conference" roots. That's a great direction for the conference to take, given the speed of change in our industry today!

Lighting is more than meets the eye. The paper session by M. Wei about color preference under LEDs with Diminished Yellow Emission was fascinating. This study took a look at the preferences of people with side-by-side comparisons of two rooms. When energy in the yellow (570-580 nm) part of the spectrum was removed, preference increased - despite a lower CRI. There are currently 22 existing metrics for color quality, but which one or combination is the right one? His summary sentence, "Brightness perception can not be predicted by luminous efficacy." has huge implications. Efficacy is not the end-all be-all? What can we learn about human perception that might allow us to provide better quality of light with fewer lumens? How do our current metrics need to change to reflect this?

The Circadian, Neuroendocrine, and Neurobehavioral Effects of Lighting seminar on Tuesday afternoon, presented by Steven Lockley prompted a great conversation between my eye doctor and me. The crossover between disciplines is becoming more important than ever. Lockley discussed the connection between the newfound photoreceptors in the eye and 440 nanometer light. So, not just any light, but this particular wavelength of light is what helps us set Circadian rhythms. This light impacts our alertness (whether or not we actually feel more alert.) Even blind or rod/cone impaired people can sense light and dark when these photoreceptors are activated. The argument that comes next is, if 440 nm is the ideal wavelength do we need to be sitting around under blue light all day long? Or can warm light sources be enhanced in the 440 nm range?

It's an exciting time to be in lighting design! The more we research, the more we discover how important lighting is. There were plenty more concepts and ideas covered at this conference. There just isn't enough room here to discuss them all. Because of the informative papers and presentations plus the friendships and energy from the Emerging Professionals in our industry, the IES Annual Conference has become a definite "must attend" for me. Hope to see you there next year - in Pittsburgh
Are you attending the LED Specifier Summit in Chicago? This one-day, seminar-packed event is a great way to pack in some continuing education credits before the end of the year. The speaker lineup is great, too. (Biased, maybe?)
Be there!
I am looking forward to two upcoming speaking engagements! I will be presenting technical luncheons for two IES sections this month - in Montreal and Toronto. I love visiting Canada and speaking about lighting. Two of my favorite things! It should be a great trip.
At last night's Illumination Awards event in St. Louis I found myself smiling until my cheeks hurt. Thank you, St. Louis lighting community for being energetic, creative, and fun!
I am so grateful for each of you. There are bunches of unique and special individuals in this group, and as a whole we are spectacular!
In the upcoming days we will be posting pictures from the photo booth and quotes from the time capsule on the IES Facebook page and Twitter to stretch out the fun just a little longer...
In the meantime, I'll be working outside on the deck surrounded by my favorite things and enjoying the sparkles of the disco ball!

This year will be my final year as the St. Louis Illumination Awards chairperson. The event is next week. I hope to see you there! Thank you for all of the support and encouragement over the last six years!!

Disruptive Innovation
           "An innovation that creates a new market."

This week an architect said to me, "I don't see any reason why a new product installed today would not be LED." While I don't necessarily agree quite yet, his point is coming true. The times we are living in now are similar to the time of Edison's lamp. The electric lamp brought the end of the gaslight industry. LEDs are bringing the end of filament and arc tube lamps. I can lament that reality or I can make sure that the the LED sources being installed today are of a quality that I want to spend the next 25 years of my life living under.
Let's get out there and specify quality LEDs before every existing socket gets filled with a poor-color, bad color temperature, flickering replacement lamp!
As Courtney heads back to school for her senior year, we asked her to write a summary about her summer at ENvisionLD. Good luck at school this year, Courtney! We miss you already!

I would like to take the time to thank Envision Lighting Design for my internship experience this past summer. I have developed valuable leadership skills, the value of teamwork, and real world experience. It has been such a welcoming and positive environment to work in.

 Working for Envision Lighting Design has allowed me to apply my knowledge from my previous internship as well as my schooling so far. I have made connections with people that I never would have had the opportunity to meet if it wasn’t for Lisa. With this experience I feel one step closer to being confident in starting my career after just one short year left of college.

Thank you!!
